How Difficult Is WordPress?

I use WordPress.COM

Its very easy but it cuts out a lot of the features I need and want.

I know that ww.wp.xz.cn is self operated right.

Im not all that smart when it comes down to Website design. So If i were to register with a host, How difficult is it to use ww.wp.xz.cn?
I dont want to get myself into anything tricky.

What are the requirements?

-Host
Etc. Please help me understand. thanks!
